Campanula plant named &#39;B. 10.082&#39;

ABSTRACT

A new and distinct cultivar of  Campanula  plant named ‘B.10.082’, characterized by its compact upright plant habit; dense and bushy plant form; vigorous growth habit; and large upright, violet flowers.

LATIN NAME OF THE GENUS AND SPECIES OF THE CLAIMED PLANT

Campanula portenschlagiana Schult.

VARIETY DENOMINATION

‘B.10.082’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula portenschlagiana Schult., commonly known as Dalmatian Bellflower and hereinafter referred to by the cultivar name ‘B.10.082’.

The new Campanula cultivar is a product of a planned breeding program conducted by the inventor, Gert Jensen, in Marslev, Denmark.

The new Campanula originated from a selfing cross made in 2010 by the Inventor between plants of the Campanula portenschlagiana Schult. variety ‘B.09.01’ (U.S. Plant patent application Ser. No. 13/067,310). The Inventor selected the new Campanula cultivar from the progeny of the above crossing in 2011 on the basis of its compact, upright growth, with low need for retardation and fungicides and distinctive flowering habit.

Asexual reproduction of the new Campanula cultivar has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘B.10.082’, which in combination distinguish this Campanula as a new and distinct cultivar:

-   1. Violet, single bell flowers; -   2. High numbers of flowers per plant; -   3. Dense and bushy plant form, mainly due to more upright stems; -   4. Upright plant habit; -   5. Less need for growth retardant.

Plants of the cultivar ‘L 10.018’ can be compared to plants of the Campanula portenschlagiana Schult. cultivar ‘B.09.01’ (U.S. Plant patent application Ser. No. 13/067,310). However, in side-by-side comparisons conducted by the Inventor in Marslev, Denmark, plants of the cultivar ‘B.10.082’ and the cultivar ‘B.09.01’ differ in the following characteristics, it must however be mentioned that the new cultivar plant examined has not been treated with growth retardant.

-   1. Plants of the new Campanula have violet, single bell, upright     flowers compared to the deep violet flowers of ‘B.09.01’. -   2. Plants of the new Campanula have more upright growth than plants     of the cultivar ‘B.09.01’. -   3. Plants of the new Campanula do not need growth retardant or     cooling treatment. -   4. Plants of the new Campanula have smaller leaves and thus less     conspicuous foliage when flowering. -   5. Plants of the new Campanula have more flowers per plant than the     plants of the cultivar ‘B.09.01’. -   6. Plants of the new Campanula appears to be less susceptible to     grey mold. -   7. Plants of the new Campanula have a shorter production time than     the plants of the cultivar ‘B.09.01’.

DETAILED BOTANICAL DESCRIPTION

The new Campanula ‘B.10.082’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 4^(th) edition, where general terms of ordinary dictionary significance are used. Plants were grown under greenhouse conditions with an average day temperature of 18-20° C., an average night temperature of 16° C., ambient (60 watt) light level, and 6 weeks of long day treatments (16 hrs). Plants used for this description were grown for about 14 weeks after cutting.
